Re: all spokes are loss and wheel wobbles side to side
You can fix it.
Truing up a wheel is not hard if you have a little patience. Google "wheel truing" or "how to true a wheel". There may be a few posts here too, not sure.
The way to avoid having all your spokes come loose is check them on occasion and tighten as needed. Also, zip ties at each cross help immencely.
Stay out of the rough stuff.
